Spread of Scientific Revolution
Tools and instruments Microscope Barometer Thermometer Medicine and anatomy Dissection of human bodies Vaccine to prevent smallpox (cowpox) Chemistry Smaller primary particles (elements) Boyle’s law explains how volume, temp, and pressure of gas affect each other

The Enlightenment Definition: a new intellectual movement stressing reason and thought and the power of individuals to solve problems

Two Views of Government
Thomas Hobbes Leviathan All humans are naturally selfish and wicked Without gov’t, life would be “nasty, brutish, and short” To have good life, give rights to strong ruler and in return receive law and order (social contract) Ruler needs total power to keep citizens under control (absolute monarchy)

Two Views of Government
John Locke People can learn from experience and improve themselves People can govern own affairs and look after welfare of society (no abs. monarchy, but self) All born free and equal with three natural rights: life, liberty, property Government has responsibility to protect rights If gov’t fails, people should overthrow it Power of gov’t comes from consent of the governed
